Data for quality-control equipment blanks, field blanks, and field replicates for baseline water quality in watersheds within the shale play of eastern Ohio, 2021–23 Data for quality-control equipment blanks, field blanks, and field replicates for baseline water quality in watersheds within the shale play of eastern Ohio, 2021–23
In 2021–23, the U.S. Geological Survey (USGS), in cooperation with the Ohio Division of Natural Resources, led a study to characterize baseline water quality (2021–23) in eastern Ohio, as they relate to hydraulic fracturing and (or) other oil and gas extraction-related activities. Water-quality data were collected eight times at each of eight sampling sites during a variety of flow...
qPCR Results for An Assessment of Pathogens in National Park Hot Springs qPCR Results for An Assessment of Pathogens in National Park Hot Springs
In 2018 and 2019, a multidisciplinary team from the U.S. Geological Survey (USGS), National Park Service, The Commonwealth Scientific and Industrial Research Organization, Montana State University’s Department of Microbiology and Immunology, and the Teton Conservation District, initiated a study to document the presence or absence of Naegleria fowleri, Giardia, Escherichia coli, and
Estimated crop irrigation water use withdrawals in Hualapai Valley Irrigation Non-Expansion Area Groundwater Basin, Arizona for 2023 Estimated crop irrigation water use withdrawals in Hualapai Valley Irrigation Non-Expansion Area Groundwater Basin, Arizona for 2023
Observations of irrigated agricultural land within the Hualapai Valley Irrigation Non-Expansion Area Groundwater Basin in Arizona. Crops were verified in situ twice in 2023, first on May 10th and again on Sep 14th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agricultural Imagery Program County Mosaic 2023 imagery for...
Concentrations of microbial source tracking markers in cattle fecal samples, western Colorado, 2023 Concentrations of microbial source tracking markers in cattle fecal samples, western Colorado, 2023
The U.S. Geological Survey is investigating sources of fecal bacteria in streams in the Grand Valley of western Colorado by using quantitative polymerase chain reaction microbial source tracking (MST) markers. The CowM2 MST marker was not detected in water-quality samples collected in 2022, which raised questions about the use of the marker for investigations in western Colorado. The...
Bottom dissolved oxygen measurements from Lake Erie's Central Basin, 2023 Bottom dissolved oxygen measurements from Lake Erie's Central Basin, 2023
This data set, compiled by the USGS Lake Erie Biological Station, provides near-bottom measurements of temperature and dissolved oxygen for the Central Basin of Lake Erie. Data were recorded by self-contained environmental data loggers (PME, Inc., MiniDOT data loggers). The data loggers for 2023 were deployed to collect data during April 2023 through November 2023 to better understand...
Telemetry detections of hatchery reared Cisco in Lake Erie with reference to temperature and predation, 2021-2022 Telemetry detections of hatchery reared Cisco in Lake Erie with reference to temperature and predation, 2021-2022
Cisco (Coregonus artedi) have been extirpated from Lake Erie since the 1960s, but they once supported one of the largest Laurentian Great Lakes fisheries. Reintroduction may be beneficial to the Lake Erie fishery, but impediments for re-establishment are not fully understood. This data set aimed to use acoustic telemetry to investigate the thermal habitat use and survival of hatchery...
